Shiprocket — RTO shipment not delivered

I m very disappointed with ship rocket services as they dont work on customer complaints properly. just delay the complaint and close it without any resolution,

this is regarding one of my RTO shipment which is not delivered to me back and on status its marked delivered on some other location address. when i informed about this they saying its delivered to me, i asked them to provide me POD where i signed, they have no answer for that just want to close the issue saying this its delivered
